950 FILICES. [ Cyathea. 
Indusium membranous, splitting irregularly, persistent at the base 
of the sorus as a shallow cup with lacerate margins.—Hook. and 
Bak. Syn. Ful. 26. 
KrrmapeEc Isnanps: Sunday Island, abundant from sea-level to the tops 
of the highest hills, alt. 1700 ft. 
A noble species, allied to C. medullaris, but sufficiently distinct in the more 
membranous fronds, in the stipes and rhachis not being conspicuously muricate 
and densely clothed on both sides with yellowish-brown deciduous wool, and in 
the fertile segments being much less coarsely serrate. 
4. C. Cunninghamii, Hook f. in Hook, Ic. Plant. t. 985.—Trunk 
8-20 ft. high, rarely more, often coated at the base with densely 
compacted aerial rootlets, upper part covered with tbe pendent 
withered fronds. Fronds numerous, 20-30, 6-10 ft. long, 2-4 ft. 
broad, 2-3-pinnate, subcoriaceous or almost membranous, flaccid, 
dark-green above, paler beneath. Stipes rather slender, dark- 
coloured at the very base, and furnished with numerous linear 
scales, elsewhere pale, and together with the rhachis slightly 
tubercled, more or less covered, especially on the upper surface, 
with pale yellowish-brown woolly or strigose tomentum. Primary 
pinne 1-2 ft. long, 4-6in. broad, oblong-lanceolate, acuminate ; 
secondary 2-4 in. long, about #in. broad, linear-oblong, acuminate, 
deeply pinnatifid above, pinnate below. Segments or pinnules 
4-1 in. long, linear, obtuse, regularly lobulate or pinnatifid ; lobules 
entire; veins forked. Sori copious, one to each lobe of the pinnule, 
rather nearer the costa than the margin. Indusium brown, mem- 
branous, at first covering the sorus, splitting up very irregularly, 
sometimes leaving an unequal-sided cup with lacerate edges, at 
other times a single lobe on one side as in Hemitelia.—Fl. Nov. Zel.

Best distinguished from C. medullaris, to which it is closely allied, by the 
smaller size, more membranous fronds, paler and much less muricate stipes and 
rhachis, which are more or less clothed with yellowish strigose hairs, and by the 
smaller segments and sori. 
5. HEMITELIA, R. Br. ~ 
Tree-ferns, not distinguishable in habit from Cyathea. Fronds 
large, usually 2-3-pinnate, rarely pinnate. Stipes smooth or 
asperous or muricate. Veins pinnately forked; veinlets free, or 
the lower ones more or less anastomosing just above the costa. 
Sori dorsal, globose, situated upon a vein or veinlet; receptacle 
elevated, globose or elongated. Indusium never covering the sorus,
